LUDWIG BERNARD, OF PRAGUE, AUSTRIA-HUNGARY.

APPARATUS FOR IMPREGNATING FIRE-IGNITERS.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed April 2, 1907- Serial No, 366,051.

To all whom it may concern:

Be it known that I, LUDWIG BERNARD, subject of the Emperor ofAustria-Hungary,

and resident of Prague, Bohemia, Austria- Hungary, have invented anImproved Appossesses a great many advantages, in that it makes the fireigniter simple and cheap, suitable for all purposes and shuts out alldanger of fire.

In the annexed drawing is shown the fire igniter, as also examples ofits construction, and impregnation device.

Figures 1 and 2 show different views of the fire igniter. Fig. 3 shows amechanical working spinning device. Fig. 4 shows an impregnation basket;Fig. 5 shows a 1s ec- 1g. 6 shows the same in plan. Fig. 7 shows adevice for cutting the single woven pieces.

For producing the fire igniter, Figs. 1 and 2, a strong rope a of flock,straw or some other such vegetable matter is used which is twistedtogether by means of the mechanical spinning device shown in Fig. 3. Thethread of the weft yarn can be replaced by the pieces of wood 6.Theipieces of wood are pushed between the single ropes from one side.The finished band is rolled. up on a roller 0 which for simplicity, isturned by the Weight (1.

The single bands can be of any width and can afterwards be cut to anyrequired length. The finished rolls 0 are then placed into a cylindricalperforated basket 6, Fig. 4, and separated by means of the thin sheavesIn these baskets the rolls are now impregnated. For this purpose a greatnumber of baskets e are placed on a truck g, Fig. 5, and

, brought near theboiler h containing the fluid impregnation mass. Thefirst basket is then lifted by means of the impregnation device ihanging on the traveler j above the boiler 72 The basket together withthe impregnation device is thendipped into the fluid impregnation mass.By means of the bevel wheels 7c, the basket is turned about itshorizontal axis a few times, so that the whole of its contents becomeequally impregnated, which with the devices used up to the present, in pwhich the basket is simply dipped-in, is prac tically not the case. Bymeans of impregnation, the basket is again raised. When the basket has,reached its highest position the truck is moved forward so far that itsend is under the basket. The basket is then let down on the truck andthe impregnation device detached. While the superabundant impregnationmass flows back into the boiler, the next basket is raised and is movedforward by means of the traveler This basket then pushes the alreadyimpregnated basket further along the truck 9 on the rails l. WVhile thetruck is pushed back, the fresh basket is in a similar manner to thefirst one dipped into the impregnation bath. The pitch still flowingfrom the first basket is led down a slanting-plane m back into theboiler. After the dipping, the basket is again raised, and the truck 9again brought forward and the above occurrence is again repeated.

By each fresh impregnated basket, the previous ones are pushed furtheralong the rails Z, so that the first and the successive baskets arepushed through a closing door a into a cooling chamber. To keep theimpregnation bath always of the'samequality and at the same level, thepitch or some such substance is melted in one or more boilers p (Fig.

-6), and in another boiler q keptat the re- From this boiler the massquired thickness. is brought into the boiler 7L through a funnel whenrequired. After they have been completely cooled, the separate rolls aretaken out of the baskets and by means of a cutting device cut intopieces of the required length and breadth. These short pieces are thenwrapped in thin paper and five or ten or more are packed together and sobrought on the market.

As large openings are left between the ropes or between the ropes andpieces of wood, the air has free access from all sides, so that thewhole fire igniter commences at once to burn and the flames thereofquickly ignite the coals. The single igniters may easily be pulled intomore parts as namely one, two or more ropes a may easily be slipped offthe pieces of wood. In consequence of this, there is a greater economyby using these fire igniters than with others which are mostly in theform of briquets or bundles or also in the form of pieces of rope whichhave been dipped in resin or some such substance and wrapped in paper.

Having fully described my invention, what I claim and desire to secureby Letters Pat ent is:

An apparatus for impregnating fire igniters in an impregnation fluid,com rising in combination, an impregnation asket, into which the variousrolls of fire igniters are placed, separation sheaves for separating thesaid rolls inside the'impregnation basket,

4 and a bevel gear actuating the horizontal axis of the saidimpregnation basket, so that the latter 'is revolved inside theimpregnation 15 fluid, and thereby the rolls are entirely and eqiiallycovered with the impregnation fluid, su stantially as described andshown and for the purpose set'forth.

In testimony whereof I have hereunto set 20 my hand in the presence oftwo subscribing witnesses.

LUDWIG BERNARD.
